ori inal application filed ctober 23,

To all whom'it inc y concern:

Be it known that I, CHARLES W. BECK, a

citizen of the United States, residing at Rockville Center,county of Nassau, State of New York,I have invented certain new and useful Improvements in Acetylene-Gwen ators, of which the following is a specification.

This invention relates to improvements in acetylene generators, and refers more specifically to an improved carbid feeding mechanism, for feeding pulverulent or 7 broken carbid.

.The object of the invention is to provide an extremely simple mechanism, of the character referred to, Containing a minimum number of movable parts and wherein the oar-bid fed through a Valve mechanism-so constructed and arranged that the 'b yof carbid is caused to bank up and seal the car: bid discharge passage when the valve mechanism moves into closed position, the parts r being .sojarrang; .13 with reference to each other, as to provide great freedom of movement and to afford little liability of becoming clogged by the oarbid.

ment contributing to the conveniency and.

efficiency of the apparatus as a whole as will more fully appear from the detailed de scription.

\ The invention consists in the matter here- Y be readilyunderstood from the following inafter described and more particularly pointed out in theappended claims and will description, reference being had to the accompanying drawings where1n:

filed December a whole a lower reservoir or receptacl'e con stituting the generating chamber, within which the carbid 1s pluzigcd into a body of liquid. 2 an elevated carbidhopper and 3 a contracted intervening tubular I support forming a chamber lwithin which the carhid feeding mechanism is located; the sevelements mentioned being constructed,

so far as their general features are concerned, in any well known or suitable manner. 1

The bottom wall 5 of the'hopper is conical and terminates at its lower end in a short tubular chute-6 forming the discharge pas sage through which the carbid is fed from the hopper. This discharge chute is deflect ed to one side so as to discharge laterally. A supporting casting 7 is connectedtdthe chute and is formed with a horizontally ex tending shaft or stud portion 8, said stud portion projecting horizontally from the upper edge of the chute. Upon this stud is journaled the feed drum 9, wherebygsaid drum will be mounted eccentrically to the discharge opening of the chute. Secured'to the chute and closing the inner end of the feed drum is a disk 10, the end of the chute projecting through said disk and discharging into the drum. On the exteriorof the drum near its outer edge is formeda beveled gear'll. The drum is provided in its'outer vertical wall with a discharge aperture 12 through which ca rbid will drop into the generating chamber when said aperture is at the lowest point of its movement during" the rotation of the drum.

In the construction illustrated herein the generator proper is arranged to communicate with a gasometer 13 forming an independent structure and the rising and falling of the bell l l'there'of is made the'motive means for automatically actuating'the carbid feeding mechanism of the generator.

To this end a drive shaft 15 is our naled to extend horizontally through the side wall of the contracted portion 3 of the generator at a point'laterally opposite the feed drum, that end of the drive shaft which projects the feed drum, as indicated clearly in the within the generator being provided. with a eter member 13 and carries at its enda spur gear 19 arranged to intermesh with a rackbar mounted vertically upon. a bracket 21' carried by the bell 14 of the gasometer.

As a convenient means of holding the gear 19 and rack 20 in mesh with each other and at'the same time aifording a suitable support for the bracket 18, a bar 21 is secured to' the lower gasometer member and arranged to project vertically some distance above the latter, and upon the upper memher or bell is mounted a guide 22 which embraces and slides upon the bar 21, as best vided in its-upper side closed by a suitable shown in Fig. 3.

' It will be obvious from the foregoing de-,

scription that the rising and falling of the bell will imparta rotary movement to the .drive shaft, first in one direction and then in the other, which motion of the shaft will impart an oscillatory movement to the feed drum, acting to carry the discharge aperture of the latter to its low point to permit carbid to drop therethrough into the generating chamber. The rack 20 is supported on the bell 14 in such a position and is so proportioned with respect to the gear 19 that when the bell rises the gear will be given one or more revolutions and the drum is so-mounted that its aperture will be at its high point with respect to the discharge chute of the carbid hopper when the rack bar 20 is disengaged-from the gear 19 by the continued upward movement of the bell.

When the bell descends by reasonof the reduction in gas pressure therein the rack bar will engage the gear 19 and rotate it in the reverse direction, thereby causing the feed drum to reverse its movement. These parts are so arranged and proportioned-that the aperture in the feed drum will be at its high point when the bell is at the limit of either of its movements.

The gasometer is placed'in communication with the gas space of the generator through a gas pipe 40 and the gasometer is likewise supplied with an outlet pipe 41 as usual. The generator is desirably provided with a filling pipe 42 for charging the generating chamber with liquid, the outer portion of said pipe 42 being arranged to extend vertically, provided with-an overflow hole 43 which servest'o indicate when the generator has been filled to the required height and also provided with a suitable cock 44. The generator is likewise provided with a discharge nozzle 45 controlled by a gate valve 46 through which the residue may be discharged and in order to facilitate the inspection and cleaning of the interior of the'generator, a manhole is progas tight cover 47. The hopper is likewise noeaeee provided with a filling aperture closed by a screw plug 48.

The operation of the apparatus constructed and arranged as described has been sufiiciently indicated in connection with the foregoing description to be entirely obvious and need not therefore be repeated at length.

It is to be. noted, however, that the construction of the carbid feedingymechanism is such that it is almost, if not quite, impossible for it to become choked .or clogged by pieces of carbid sma'll enough topass through the feed opening, since there is no limit to the extent of rotary movement of the feed drum except that imposed-by the limits of movement of the asometer bell. It will'be clear also that the feeding mechanism will serve to maintain itself sealed at all. times, except when actually discharging, as long as a supply of carbid remains in the hopper.

and produce with all a simple and economically constructed generator requiring but little skill in its manipulation, and therefore, well adapted for general use.

While I have herein described what I deem to be a preferred embodiment of the invention, yet it will be obvious that the details of construction may be modified to some extent without departing from the invention, and I do not, therefore, wish'to be limited to these details, except to the extent that they are made the subject of' specific claims.

The subject matter of the invention described herein forms a part of my original application, Serial No. 7 9,626, filed October 23d,1901, of which original application this is a division.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a carbid feed mechanism the combination with a carbid receptacle provided with a discharge chute, of a drum mounted on a horizontal axis, the discharge chute delivering carbid into said drum below the axis thereof whereby the drum will be eccentric to the discharge chute, the drum being provided with a discharge opening in an expansible and collapsible gas holder,

and means whereby the movement of said gas holder will rotate the gear.

2, In a carbid feed mechanism the combination with a carbid receptacle provided It will be seen from the foregoing that I attain the several objects of the invention with a laterallv extending discharge chute,

of a drum mounted on a horizontal axis and eccentrically to the axis of the discharge chute, the said chute extending-into said 1,oes,eee

drum near the lower wall thereof, the drum being provided with a discharge opening in outer vertieal Wail, end means actuated by variations in gas pressure to rotate the m, whereby carrfid will be inter-- mu: w iv alsehergeii from Sfild drum when the :11 hsrge opening thereof is at the low pomi; 111. 11s revoiutlon am the olscharge chute will be sealed by eerhid, when the discharge opening in the drum is at the 10 high point in the rotation of the drum.

In testimony whereof I hereunto affix my signaiure in the presenoe of two Witnesses this 16% day of December, 1908.
